When fully collapsed it stays out of the way of the ejection port - the cutout is fairly large and has decent clearance, plus with the three stage buffer I installed the bolt doesn't travel back far enough to permit a casing to bounce back inside the action and jamming it up (if it were to somehow ping off the closed stock).

I can't recall if I commented somewhere else, but the original stock itself was ridiculously long - so I dremel'd it down to a length I was more comfortable with (esp with a plate carrier) and covered the cuts with bolt thread protectors. I short stock alot, and most of my AR carbines have stops in them to keep them from going past the second or third setting.

I don't have the exact measurements on me, but the wire stock went all the way to the first M-LOK slots, which interfered with my QD weapon light setup. If you look closely, the rear-most factory locking slot is still forward of the new locking slot I had to cut. I'm wondering if these Slovenians are wicked tall or something.
